Abstract

The Sangdong deposit consists of metamorphosed lenticular beds in a sequence of gently dipping argillaceous sedimentary rocks. It is believed that scheelite mineralization was simultaneous with metamorphism, followed by deposition of wolframite during a later hydrothermal phase. The reserve of ore is estimated to be 3,000,000 tons, containing 51,000 tons of WO (sub 3.)
